About

Justin is a self-taught full-stack developer and founder of KoponTech. Building since 2022.

He got his start in computers through gaming and console scripts, and never stopped. When he started building full-scale apps, he learned MySQL offline, on his phone, reading local HTML files with no internet. That stubbornness defines how he works.

He has built 100+ projects solo: AI apps, developer tools, mobile apps, and client websites, reaching 1,000+ combined users. Notable work includes Cook AI (Google Play) and Abi (Flutter). He has integrated every major payment provider: Stripe, PayPal, LemonSqueezy, Polar, and more.

Beyond solo work, he has collaborated with US & EU teams in hackathons, was invited to compete internationally, and worked with Jeremiah Welch (Creative Director) on a project called NourAIsh. He also has a sales background, reaching Top 2 in his group, so he knows how to talk to real users, not just build for them.
